Yamaha CS1x

From Wikipedia, the free encyclopedia

The Yamaha CS1x is a sample-based synthesizer released by the Yamaha Corporation in 1996. The CS1x was one of the first digital synthesizers to have knobs again. Most earlier digital synthesizers often featured menu-based systems to manipulate sound parameters, with an interface consisting of a handful of keys and a screen, the CS1x's design takes inspiration from many Sequential Circuits synthesizers, using a grid of paramaters printed on the panel which are utilized by rotary switch as a row select, and a pair of buttons at the base of each column to edit that particular value. This interface allows an experienced user to edit the synthesizer efficiently and quickly.

Its synthesis is based on the Yamaha XG engine, with some extra 'Material Waveforms' to suit analogue synthesizer emulation. The CS1x's presets mainly feature nineties eurodance sounds. Whilst many of the preset sounds dated quickly, many were based upon classic polysynth textures and have remained generically useful and timeless.

The Yamaha CS1x was superseded by the Yamaha CS2x in 1999.
